BACKGROUND: Indications for use of tolvaptan in SIADH-associated hyponatraemia remain controversial. We audited our local guidelines for Tolvaptan use in this situation to review treatment implications including drug safety, hospital admission episode analysis (episodes of liver toxicity, CNS myelinolysis, sodium-related re-admission rates), morbidity; mortality and underlying aetiologies. METHODS: We report a retrospective case series analysis of on-going treatment outcomes (case-note review) for 31 patients (age 73...

BACKGROUND: Cerebral salt-wasting syndrome (CSWS) was initially described over 60 years ago in hyponatremic patients with a cerebral lesion. However, the diagnostic criteria for CSWS have not been fully established. Thus, when hyponatremia is observed in patients with CSWS, they may be misdiagnosed as having the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Thus, it is critical to differentiate between these 2 conditions because their treatments are diametrically opposed...

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) may develop in association with several malignancies. However, as an immunohistochemical analysis is not performed in the majority cases, its true cause is often uncertain. We herein report a case of SIADH following chemotherapy due to tumor-derived ADH production in a patient with mucosa-associated lymphoid tissue (MALT) lymphoma. A retrospective immunohistochemical analysis demonstrated ADH expression by lymphoma cells. These findings highlight the importance of using an immunohistochemical analysis to determine ADH production by tumor cells in patients with SIADH...

BACKGROUND: Treatment options for chronic SIADH include water restriction (WR) and urea. The usefulness of urine osmolality to guide the choice of the treatment option is not clearly defined. We hypothesized that urine osmolality can indicate whether treatment with mild water restriction alone could be successful. METHODS: Retrospective Review of clinical and biochemical (blood and urine) data of patients with chronic SIADH treated for at least one year with mild WR (1...

Antidepressants are routinely used by General Practitioners (GP) as well as Psychiatrists to treat Depression. They are tolerated well. However, in certain patient populations, they are associated with SIADH (Syndrome of Inappropriate Anti-Diuretic Hormone Secretion) and Hyponatremia. Various research studies have shown that all antidepressants are associated with Hyponatremia. Hyponatremia as a side effect of antidepressant therapy is more commonly seen in old age, chronic Kidney disease and Hypothyroidism...

Hyponatraemia is a well-established and potentially, a life-threatening adverse effect of selective serotonin receptor uptake inhibitors (SSRI). However, its occurrence secondary to syndrome of inappropriate antidiuretic hormone secretion (SIADH) with escitalopram, has been reported extremely sporadically. The reporting of such rare, but life-threatening adverse effects of escitalopram assumes immense significance in light of the fact that SSRIs presently form the mainstay of treatment of depressive disorders...

Syndrome of inappropriate antidiuretic hormone (SIADH) and cerebral salt wasting syndrome (CSWS) as the two most common neuroendocrine diseases, have been recognized and understood by many neurologists. Although SIADH and CSWS are the common causes of central hyponatremia after traumatic brain injury (TBI), a few cases are mixed, with the coexistence of the two pathological pathomechanism. However, the mixed type of both SIADH and CSWS has not been clearly reported in any literature. Here, we present the first description of the concurrent syndrome of SIADH and CSWS after TBI in four patients who underwent standard diagnostic procedures, treatment and follow up...

We describe two polytrauma patients without severe head trauma who developed Cerebral Salt Wasting Syndrome (CSWS) during their stay in our ICU with natriuresis, hyponatremia and hypovolemia. Hyponatremia encountered in CSWS and the syndrome of inadequate antidiuretic hormone secretion (SIADH) is a common electrolyte finding in patients with severe head trauma, subarachnoid hemorrhage, malignancy and infections of the central nervous system. CSWS was an unexpected electrolyte finding in our patients with minor head trauma without neurological or neurosurgical problems...

Association of SIADH with malignancy was first reported in 1957, when it was described in two patients with bronchogenic carcinoma. While the association with small cell lung cancer (SCLC) is well known, that with non small cell lung cancer (NSCLC) has been rarely reported. We report a case of 70 year old male who was found to have hyponatremia secondary to SIADH. Radiological tests revealed right hilar lung mass with mediastinal adenopathy. Bronchoscopic biopsy revealed non-small cell lung cancer of type squamous cell...

Neuroendocrine tumors can arise from any portion of the gastrointestinal tract including the colon and rectum. In the scope of all colon and rectal malignancies, they are a rare cause of colorectal carcinoma. Relating to their pluripotent neuroendocrine cellular origins these carcinomas can produce a variety of biologically active peptides with several resultant paraneoplastic syndromes. One of these paraneoplastic syndromes is the syndrome of inappropriate antidiuretic hormone (SIADH). In the SIADH, supraphysiologic levels of vasopressin (antidiuretic hormone, AVP) precipitates exorbitant free water retention and resultant electrolyte abnormalities, most notably hyponatremia...

In the syndrome of inappropriate antidiuretic hormone secretion (SIADH), hyponatremia is limited by onset of vasopressin-escape caused by loss of the water channel aquaporin-2 in the renal collecting duct despite high circulating vasopressin. Here, we use the methods of systems biology in a well-established rat model of SIADH to identify signaling pathways activated at the onset of vasopressin-escape. Using single-tubule RNA-Seq, full transcriptomes were determined in microdissected cortical collecting ducts of vasopressin-treated rats at 1, 2, and 4 days after initiation of oral water loading in comparison to time-control rats without water loading...

Hyponatremia is the most frequent electrolyte disorder with the syndrome of inappropriate antidiuresis (SIADH) being its predominant cause. Physiological studies in patients with SIADH are difficult to interpret due to usually several comorbidities and polymedication. Therefore, a SIADH model in healthy volunteers would be very helpful to allow insight in this complex disease and to test new therapeutic approaches. The aim of the study was to create a SIADH model with evaluation of subsequent physiological changes...

PURPOSE: Tolvaptan (TLV) is indicated to treat hyponatremia due to syndrome of inappropriate diuretic hormone (SIADH) in Europe. Treatment is to be initiated at 15 mg QD but post-approval reporting indicates increasing use of 7.5 mg as the starting dose. Physicians believe 7.5 mg is effective and has a lower incidence of overly rapid correction of serum sodium. METHODS: Single TLV doses of 3.75, 7.5, and 15 mg were administered to 14 healthy adults in a crossover design and to 29 subjects ≥18 years with SIADH and serum sodium between 120 and 133 mmol/L in a parallel-group design...

WHAT IS KNOWN AND OBJECTIVE: Several studies have reported that itraconazole-induced inhibition of vincristine (VCR) metabolism might result in neurological impairment and syndrome of inappropriate antidiuretic hormone (SIADH). However, there are few reports concerning adverse drug reactions (ADRs) resulting from concomitant use of vindesine (VDS) and itraconazole. Here, we report the first case of adverse drug interactions (ADIs) between itraconazole and VDS in a Chinese child with acute lymphocytic leukaemia (ALL)...

BACKGROUND: Ecstasy (Ec) use produces hyperthermia, excessive sweating, intense thirst, an inappropriate antidiuretic hormone secretion (SIADH) and a multisystemic toxicity due to oxidative stress (OS). Intense thirst induces high intake of pure water, which associated with SIADH, usually develops into acute hyponatremia (Hn). As Hn is induced rapidly, experiments to check if Ec acted directly on the Inner Medullary Collecting Ducts (IMCD) of rats were conducted. Rhabdomyolysis and OS were also studied because Ec is known to induce Reactive Oxygen Species (ROS) and tissue damage...

Syndrome of Inappropriate Secretion of Antidiuretic Hormone (SIADH) is one of the most common causes of hyponatremia in hospitalized patients. The distinct aetiologies and co-morbidities associated with hyponatremia pose substantial challenges in identifying and managing this disorder. Several infectious causes of SIADH are reported but hyponatremia associated with SIADH and influenza virus infection is less commonly seen. We present a case of hyponatremia associated with influenza, which was subsequently diagnosed as SIADH...

PURPOSE: Pure small cell neuroendocrine carcinoma of the prostate is a rare entity characterized by a poor prognosis due to early metastatic spread as well as resistance to treatment. Considering its increasing occurrence, clinicians should be aware of its aggressive behavior, the relevance of an early diagnosis, and proper management. METHODS: A 71-year-old man treated with brachytherapy for localized low-risk prostate cancer developed widespread disease 7 years later with a prostate-specific antigen-negative neuroendocrine small cell phenotype...
